Site reporting guidance has been revised to assure accurate reporting. "The periods of time where maintenance impacted the functionality of the EOF are as follows: 1. April 30 to May 1, 2009 for approximately 36 hours due to condenser and air handler replacement. 2. January 14 to 18, 2010 for approximately 96 hours due to damper and ductwork replacement. 3. November 17 to 19, 2010 for approximately 72 hours due to a compressor failure. "This event is reportable per 10CFR50.72(b)(3)(xiii) as described in NUREG-1022, Rev. 2 since the work activities affected an emergency response facility for the duration of the maintenance. "The Senior Resident Inspector has been informed." * * * UPDATE ON 10/30/2012 AT 0940 FROM JOHN CAVES TO DAN LIVERMORE * * * "On several occasions between August 4, 2009, and November 9, 2011, the Emergency Operations Facility (EOF) ventilation systems were in a degraded state and/or removed from service, for extended periods of time. There were no actual emergencies that occurred during those periods that required activation of the EOF. "A calculation indicated that with the degraded air conditioning system during summer conditions, the temperature in the EOF could reach 87 degrees F. While there is no specific temperature limit for EOF habitability, an elevated temperature is of concern when emergency response organization members are under potential stress, as in emergency response situations. "On January 25, 2010, Harris staff found a damper in the ventilation system stuck in the nearly closed condition. The damper was reopened on the day it was discovered. A calculation indicated that with the ventilation system in the normal mode and the damper stuck, the carbon dioxide concentration in the EOF could have exceeded 0.5%. "The elevated carbon dioxide concentration due to the stuck damper, combined with the stress associated with an actual emergency in a facility and temperatures of 87 degrees, had the potential to impair a key responder's ability to perform an assigned emergency response function." The licensee has informed the NRC Senior Resident Inspector. Notified R2DO (Musser). | Non-Agreement State | Event Number: 48432 | Rep Org: ANDERSON ENGINEERING INC Licensee: ANDERSON ENGINEERING INC Region: 3 City: SPRINGFIELD State: MO County: License #: 24-20063-01 Agreement: N Docket: NRC Notified By: STEVEN BRADY HQ OPS Officer: VINCE KLCO | Notification Date: 10/22/2012 Notification Time: 16:48 [ET] Event Date: 10/22/2012 Event Time: 11:30 [CDT] Last Update Date: 10/22/2012 | Emergency Class: NON EMERGENCY 10 CFR Section: 30.50(b)(2) - SAFETY EQUIPMENT FAILURE | Person (Organization): PATTY PELKE (R3DO) FSME EVENTS RESOURCE (EMAI) | Event Text DAMAGED NUCLEAR DENSITY GAUGE "Incident: At approximately 1130 CDT, at the new Joplin High School Construction Site in Joplin, Jasper County, Missouri, a nuclear density [gauge] was run over by a tire of a towed scraper. The damage was primarily to the housing of the meter. The technician immediately secured the area and contacted his supervisor. [The supervisor] went to the site and took readings using a TROX-A-LERT Model 3105B Radiation Survey Meter of the gauge and the soil where the gauge was run over and of the scraper which ran over the [gauge]. Readings at 1 meter from the [gauge] ranged from 0.12 to 0.20 mrem/hr. A reading of 2.5 mrem/hr [was indicated at the] housing of the [gauge] . The source did not appear to be damaged and was still encapsulated in the [gauge]. "The gauge was placed in a truck box mounted in the bed of a pickup truck and taken back to [the licensee's lab]. Once at the lab the gauge was wrapped in lead sheeting and placed in a nuclear [gauge] storage box. A reading of 0.1 mrem/hr was obtained at 1 meter with the lead sheeting wrapped around the meter."

"Salem Unit 1 was operating at 100% reactor power when a loss of 4 condenser circulators required a manual reactor trip in accordance with station procedures. The cause of the 4 circulators being removed from service was due to a combination of high river level and detritus from Hurricane Sandy's transit. "All control rods inserted. A subsequent loss of the 2 remaining circulators required transition of decay heat removal from condenser steam dumps to the 11-14 MS10s (atmospheric steam dump). Decay heat removal is from the 11/12 Aux Feed Pumps to all 4 steam generators via the 11-14 MS10s. 11/12/13 AFW pumps started due to low level on all steam generators due to shrink from full power operation (this is a normal response). All safety related equipment functioned as expected. No one has been injured. As an additional note, Hurricane Sandy had recently moved past artificial island. Salem Unit 1 is currently in Mode 3. Salem Unit 2 reactor is currently in its 2R19 refueling outage and is shutdown and defueled with no fuel movement in progress." The licensee has notified the NRC Resident Inspector. * * * UPDATE ON 10/30/12 AT 0835 EDT FROM JOHN OSBORNE TO DAN LIVERMORE * * * "At 0513, following [a] Unit 1 manual [reactor] trip due to loss of condenser cooling, a manual steam line isolation was initiated due to a high condenser back pressure. All main steamline isolation valves responded as expected. The high condenser back pressure resulted in the #11 low pressure turbine rupture disc relieving. Unit 1 remains in mode 3 with Reactor Coolant System temperature at 549 [degrees] and stable. Reactor Coolant System pressure is 2235 psig and in automatic control. Pressurizer level is on program at 26 percent level and in automatic control. Core cooling is via aux feed water and the steam generator levels are on program. There were no [personnel] injuries."
